High throughput processing of polymer and composite materials by high power nanosecond UV pulses

In this paper, we will present results achieved with a high-power nanosecond UV laser source to process CFRP and PET materials. A parametric study will be presented, comparing the effects of various pulses from 2ns to 20ns and evaluating the interest of burst of pulses. We will show the interest of short nanosecond pulses for high quality and high speed processing compared to classical long nanosecond pulses.
